摘要

A proposed method for securely and efficiently sharing power dispatching data utilizes an alliance blockchain. The framework begins with the data perception layer, which collects and cleans power dispatching data by correcting errors and removing duplicates. Next, the network transmission layer employs the Grid Data Transfer Protocol (GridFTP) for secure transmission to the energy blockchain layer, using third-party authentication and distributed storage across various alliance chain nodes. The data is encrypted using the CryptoNote protocol to ensure security. The sharing layer differentiates access based on source; it exposes the blockchain-stored data to external users through an API interface and to internal personnel via digital signatures from authorized nodes. Experimental results demonstrate that this method facilitates remote sharing of power dispatching data while fully ensuring data security. In the event of an attack, the system quickly encrypts the data to prevent theft without compromising operational efficiency. Additionally, it efficiently handles high data volumes within blocks, ensuring rapid storage capabilities.
